Every workout i try to add at least one rep for every set and when i reach 12 10 8 6 i add weight. During the summer it worked great but then i had to stop training for two months because of an injury and now i'm back again.
I'm not trying to get huge and i don't care if i can lift 500pounds for deads i just lift because i enjoy it and looking better is always welcome.
What i did is instead of 5x5 i do less sets with more reps. Because of the very litle rest between sets i can't do 10reps for three or four sets.
